PROBLEM TO BE SOLVED: To develop a removal tool of coating of a tongue in mouth cavity, which has a simple shape and an easy-to-use handgrip for easily removing the coating of the center (groove part) of the tongue and is washed after use of the removal tool and prevents and removes bacteria in boiled water. SOLUTION: The removal tool of coating of a tongue is integrally formed with a removal piece (41) of a resin material having a height (about 7 mm) by a thickness (about 2 mm) and a flat handgrip (23) with a gradient (θ≈15 degree). Additionally, a protrusion (ϕd) is provided on the outside of the middle of the height of the removal piece, and a fixing piece (42) for "scratching the tongue" of the center groove on the tongue is mounted on the removal piece (41) to provide the tool. The "fixing piece" has a U-shaped cross-section, and the outer space is clipped with the coating removal piece (41) and the long edge has a gentle convex shape (hemispheric) along the central upper groove of the tongue, and the short end surface is combined together with theϕd protrusion (46) of the coating removal piece (41) in the middle of the height with a fitting hole (44).
